Ancistrus sp. Super Red

A Little More Information...

Ancistrus sp. Super Red is a highly popular captive-bred variety valued for its intense red-orange coloration and short fins, which explains its other common name, Short Fins. This small suckermouth catfish spends much of its time on hard surfaces, grazing on algae and biofilm. Peaceful, hardy, and generally easy to feed, it fits well in a mature community aquarium. Its availability is relatively common in the aquarium trade. Like other ornamental Ancistrus lines, it should be kept in clean, well-oxygenated, stable water with wood, shelters, and regular maintenance.

General species description

Ancistrus sp. Super Red is a commercial red form of Ancistrus, a South American loricariid catfish. The term sp. indicates that the fish is sold without a precise species identification; Super Red mainly refers to its selected coloration. This variety is valued for its relatively uniform appearance and discreet behavior. It is most active during the evening and at night, although it may appear during the day in a well-furnished aquarium. Like other Ancistrus, it uses its suckermouth to attach to surfaces and rasp biofilm. A mature aquarium with wood, hiding places, and good water movement suits it well. The Short Fins form has normally proportioned fins rather than extended veil-like fins.

Geographic origin and biotope

The Super Red variety is a captive-bred line rather than a natural population linked to a specific river. It is generally associated with the South American Ancistrus trade, with Colombia provided as the geographic reference for this profile. In the aquarium, aim to reproduce the broad conditions of a tropical stream: clean water, moderate circulation, shaded areas, and many grazing surfaces. Roots, smooth stones, and sturdy plants create a useful environment. Efficient filtration and regular water changes are important because this fish produces a noticeable organic load despite its modest size.

Precise locality and local name

The trade names used are Super Red, while Short Fins or Shortfin describes the fin shape. These are commercial names and are not Colombian local names connected to a known wild locality. To avoid confusing this variety with a wild form, it is best identified as Ancistrus sp. Super Red or Ancistrus Super Red Short Fin. The Colombian reference places the commercial line in a South American context, without providing a collection locality to include in its identification.

Appearance and physical characteristics

The body is stocky and flattened along the underside, with bony plates typical of the Loricariidae. The lower mouth forms an effective sucker, adapted for grazing surfaces. Color ranges from brick red to reddish orange, with intensity varying according to the line, age, lighting, and overall condition. The fins are short, without dramatic extensions, explaining the name Short Fins. Adult males usually develop fleshy tentacles on the snout; these are much less developed in females. The general shape resembles that of common captive-bred Ancistrus, but its coloration clearly sets it apart.

General diet

Ancistrus sp. Super Red is primarily herbivorous with an omnivorous tendency. Its diet should be based on quality vegetable wafers, sinking foods for bottom fish, and blanched vegetables such as zucchini, cucumber, or spinach. Natural wood is useful in the aquarium and supports digestion in many loricariids, although it does not replace a complete diet. Biofilm and naturally occurring algae supplement the menu, but a clean aquarium may not produce enough food on its own. Feed mainly after the lights go out to reduce competition. A varied, fiber-rich diet offered regularly helps maintain good condition and a stable red coloration.

In your aquarium

To succeed with Ancistrus sp. Super Red, provide a mature aquarium with roots, hiding places, and grazing surfaces. Keep the water stable, well oxygenated, and low in waste. Offer vegetable food regularly, especially in the evening, and remove uneaten vegetables. Males may defend a cave during breeding, so several males require enough shelters and space. This colorful variety is a good choice for a peaceful community aquarium when kept by an aquarist who understands that it is not simply an algae-eating fish.
